Anthocyanins and proanthocyanidins synergistically inhibit the growth of gastric cancer cells in vitro : exploring the potential physiological activity of grape and red wine

value. Mechanistically, M35GC and procyanidin C1 significantly induced cell apoptosis by reducing the ratio of Bcl-2/Bax, blocked cell cycle in G0/G1 phase by decreasing CDK4 protein and decreased glucose consumption and lactate production during aerobic glycolysis through suppressing the expression of HK2 protein in MKN-28 cells. In conclusion, induction of cell apoptosis and cell cycle arrest, as well as the inhibition of HK2 protein that participates in the glycolytic pathway and the suppression of aerobic glycolysis by M35GC and procyanidin C1 contributed to the anti-cancer effects in gastric cancer.
